I figured out a way to keep all varmints, rodents, pest, predators, and whatever else you dont want eating your corn to stay out of your corn! Here's how Take a bucket and cut a hole in the bottom.Make the hole about 3 inches in diameter. Take a rope and tie the rope to a tree limb above the spot you want your feeder to be. Tie the rope to the bucket and hang the bucket where the hole you cut is facing down towards the ground.Hang the bucket about 3.5 to 4 feet from the ground. Put a plunger in the top of the bucket with the plunger stick facing down through the hole you cut in the bottom of the bucket. Saw off all the plunger stick except for about 2 inches. Put a mineral lick under the bucket. So when the deer come to feed on the mineral lick, they will bump the plunger stick with theit anlers or head. When the plunger stick is hit, it will cause it to lift up and corn will pour out. Once this happens, deer will figure out how to get corn and you will have no more others animals eating up all your corn!
